CMC polymer is used as an additive to decrease water loss and mud-cake-thickness in mud drilling. In this study, the effect of CMC and CMC nanoparticles on water loss and mud-cake-thickness in mud drilling is investigated. CMC nanoparticles are made by using of ball milling and their size is measured by Particle size analyzer. CMC and CMC nanoparticles which were prepared by Hamilton batch mixe...

Background: Osteoporosis one of the postmenopausal symptoms is characterized by bone loss. There is a link between excessive reactive oxygen species (ROS) formation, estrogen deficiency due to cessation of ovarian function and bone loss. Free radicals are responsible for causing osteoblast apoptosis and reducing osteoblastogenesis in bone remodeling. Vitamin E is a potent antioxidant with the a...

obstructive sleep apnea (osa) together with metabolic disorders is common in severely obese patients. weight reduction is considered as a treatment modality in these cases while few of them can succeed in considerable weight loss. here, we present a severely obese man with body mass index of 54 suffered from osa, type 2 diabetes, hypothyroidism, and hypertension. he intentionally lost 80 kilogr...

electrical steels are important alloys widely used in electrical instruments. the magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of goss texture ({110} ).the direction of is the softest direction for magnetism.  in this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...

background: fractures of distal radius are one of the most common fractures seen by physicians and account for 20% of all fractures seen in the emergency room. various factors contribute in secondary displacement of fracture fragments after anatomic or near anatomic close reduction and cast immobilization in distal radius fractures. this study was designed to examine the correlation between rad...

Fenfluramine, an anorexigenic agent, is widely used in the treatment of obesity. Besides its anorectic effect, it may also have some effects on general metabolism with the consequence of weight loss. In this study, the effect of fenfluramine on the concentrations of some parameters related to carbohydrate metabolism was investigated. It was shown that the serum insulin level was reduced by ...
